In conjunction with Fig. 2, Fig. 3 and Fig. 4, Fig. 4 has disclosed in terminal TU Trunk Unit 3 inside, the concrete structure of monitoring unit 32 and operation principle.This monitoring unit 32 comprises traffic detection unit 321, telephone traffic unit 322, comparing unit 323, memory cell 324 and scheduling unit 325.
Thereby, described comparing unit 323 is used to detect described real time telephone traffic whether greater than first kind carrier channel number and export comparative result, its output result for example adopts true value and two kinds of forms of falsity in this enforcements, but in view of the above just the uniqueness ground current first carrier information source 1 of sign whether be in busy or whether not busy state, its first kind carrier channel is enough to offer this first area of space, 10 uses.
Can discern differentiation to first kind carrier channel that is derived from first carrier information source 1 contained in the upward signal in first area of space 10 and the second class carrier channel that is derived from second carrier information source 2 in order to make terminal TU Trunk Unit 3, an if described memory cell 324, be used to store the search characteristic information of the first and second class carrier channels, dispatch when comparing for comparing unit 323, also carry out necessary utilization simultaneously for scheduling unit 325.
In the present embodiment, telephone traffic unit 322, comparing unit 323, scheduling unit 324 and memory cell 325 are integrated in same monitoring host computer unit 320 jointly, that for example addresses previously can realize by a computer system that is loaded with special-purpose software, and is connected being connected with realization and described traffic detection unit 321 with trunking 3 by 485 data types.Certainly, as another kind of execution mode, also this monitoring host computer unit 320 directly can be integrated on the special chip of these trunking 3 inside and use.
The transmission of signal has the process of format conversion in the scheduling unit 325, also be, its at first the mode by RS-485/E1 conversion the control signal of RS-485 form is converted to E1 communication data form, via the described first wireless communication link L1, from the remote microwave indoor unit 35 of terminal TU Trunk Unit 3 to its follow-up outdoor unit 36 to aerial radiation.
Then, in conjunction with Fig. 5, Fig. 5 has disclosed the processing procedure of control signal in radio frequency stretch system 23, Fig. 2 second carrier information source 2 places, after the outdoor unit 236 that is connected with near-end microwave indoor unit 235 among Fig. 3 in it receives the data-signal of this E1 form, be transferred to this near-end microwave indoor unit 235, then be transferred to Base Band Unit 231, with above-mentioned monitoring host computer unit 320 in like manner, the data-signal of this E1 form is converted to the control signal of RS-485 communication data form by Base Band Unit 231 inside or external monitoring host computer module 2310, after resolving by monitoring host computer module 2310, come downwards to extension unit 232 via the down link 23D of Base Band Unit 231 inside.
After extension unit 232 received control signal after this parsing, the monitoring host computer module 2320 under it is transferred to was carried out.Monitoring host computer module 2320 is subjected to the effect of the control signal after this parsing, according to true value or falsity state that it characterized the second class carrier channel is carried out unlatching or shutoff operation.
Under the initial condition, perhaps under the general state, the second class carrier channel can be in closed condition with respect to trunking 3.For in the down link 23D of radio frequency stretch system 23, the open and close of the second class carrier channel realize by the following method:
Be preset with the tables of data of the pad value of each carrier channel in current down link 23D in the second class carrier channel in the monitoring host computer module 2320, when the control signal after resolving arrives, monitoring host computer module 2320 is upgraded the pad value of each corresponding carriers channel in this tables of data, then send a signal to the digital up converter 2321 among the down link 23D, pad value by 2321 pairs of concrete carrier channels of difference of this digital up converter is controlled, and just can realize the unlatching or the shutoff operation of carrier channel.
In order to prevent the needs of device security, digital up converter 2321 is when decaying, and the pad value of corresponding each carrier channel is decayed several times step by step.When monitoring host computer module 2320 sent these up-conversion module 2321 certain carrier channels of unlatching of instruction indication, this up-conversion module 2321 reduced the pad value of this carrier channel step by step, its gain is improved constantly until this carrier channel open, and just can come into operation.On the contrary, close certain carrier channel if desired, then only need to send corresponding instruction by monitoring host computer module 2320, the pad value of up-conversion module 2321 corresponding these carrier channels of raising reduces its gain and gets final product.Certainly, as exist a plurality of extensions when the overlay network of the base station 21 of second carrier information source 2, in the down link of certain carrier channel at current overlay network, enabled/when closing, for the down link of other overlay network, this carrier channel just should be in closes/stand-by state, also promptly, in the up-conversion module of the down link of other overlay network, the pad value of this carrier channel is carried out adaptive adjustment and make it to close, to avoid producing conflict.
More perfect, in the monitoring unit 32 of terminal TU Trunk Unit 3, in the time of the described comparison threshold value of user preset, also can be to the default simultaneously telephone traffic unlatching value of its comparing unit and a telephone traffic close value, the meaning that telephone traffic unlatching value is characterized is meant when the real time telephone traffic number among the current up link 31U that compares with it during greater than this telephone traffic unlatching value, scheduling unit 325 should send characterize true value control signal to open the second class carrier channel to use for first area of space through current trunking 31; In like manner, the meaning that the telephone traffic close value is characterized is meant when the real time telephone traffic number among the current up link 31U that compares with it during less than this telephone traffic close value, scheduling unit 35 should send characterize falsity control signal to close carrier channel.Special situation is traffic unlatching value and telephone traffic close value equivalence, also is the situation of above-mentioned acquiescence.
